The authors examined the concentration of ER and PR in malignant endometrium and compared them to the survival of the patients with endometrial carcinoma. The results were 55.5% positive ER and 44.5% negative, PR-74.1% positive and 25.9% negative. From 54 women with EC-7 died during 3 years period of time. From these 7, only one was with elevated concentrations of both ER and PR. 5 women were with negative PR and in 3-negative both ER and PR. It's considered that negative PR are the most important prognostic signs for the survival of patients with EC.
